Multibody SImulations

[Kelvin Eloho]

Hi,

I am quite new to using Gerris. I have a question which relates to multibody implementations on Gerris. 

Basically, I will like to know how to get output data for different quantities on different solids in the domain.

I have 3 solids defined in a domain and will like to get the pressure forces acting on each of them.
